Hi,
Yes, Suse have taken the policy of making the current versions of their distro quite hard to get hold of simply because they want to get everyone to buy the boxed sets. It is also known that, unlike many other distros, they don't like new Suse versions being put on magazine cover CDs and so on either.
As far as I know, this is still in accordance with the GPL which doesn't insist that people distribute via ftp and allows charges to be made for distribution media, etc.
Regards
